3rd trimester-tired and moody

I am now 33 weeks and i have barely slept i can barely work and i cut my hours down to 32 hours a week because I am a high risk. I am a diabetic thats insulin dependent. I am ready to give up on work i want to cry. I think its just my hormones but of course im not sleeping. Ive tried taking naps,coffee (1 cup),i cut my work hours down and its still not helping. I dont know what to do anymore. I even went to a therapist just so i can talk to someone even though my husbands here i dont want to get post mortem depression. Is there anyone that has the same experience or maybe seem this is my first im more stressed i dont know
